The top `lf2 has a pair of openings H, one over each of the receptacles through which the .syrup *is ponred. Removable covers I3 cover the openings. The dispensing faucet '24 is 'anchored 'by bolts and `n`111`ts`25`t0 .the `front wall I4.' The disp :nsin'g faucet `comprises-a m'ain body portion 2 6, formed preferably of a single or solid piece of metal, hav'- ing'apair 'of sides`21 extendingupwardly beyond "the top 'of )the body portion and between'which are rockably mounted on a pin 28 'the three actu'ating 'members 2-9, '30 and .31, best shown in Fig. 5; VThe center member 30 has opDQsitely i extending :lips 32 which form aninvertedT shape ameter than the bore 31o to provide spaceor passageway 48 therebetween for passage of the syrup, to be described. The valve 46 has a slotv I1 against which the washer 41 seats to provide a seal tight` fit for the valve 46. The valve has -a smaller divv is constricted and supports a ring 19, having a plurality of inwardly directed projections or teeth 80 which direct the stream in a straight line.

The operation of this construction will now be described. A

When the center handle 35 is moved forwardly,

the actuating member 30 will pivot forwardly on the pin 28 engaging the head 56 and depressing the valve stem 55. The two actuating members p29 and 3I will not be effected but will remain in theirl normal elevated position. When the valve stem 55is'depressed, the valve 58 is moved down- 49 for engagement by a screwdriver 'for -adjusting the valve and stem.

The lower portion of the bore 31b is to receive a tubular non-drip nozzle 50, having a bore 5| and an enlarged lower bore 52'. An adjustable needle valve 53 is transversely positioned with respect to the boreand'is spaced fromthe bottom of the nozzle to permit the proper flow of syrup. The two syrup control mechanisms positioned 'on the opposite sides are identical in construction and operation.

The valve mechanism for controlling thedispensing of the charged water is shown in Fig. 4 and is substantially similar to the syrup faucet valve mechanism 4I. The bore 38 communicates with a reduced bore 38a and an enlarged bore 38h. The valve operating mechanism, generally indicated at 54, includes a valve stem 55 having a head 56 which slides in the bore 38 and is held in its raised position'by a coil spring 51 which rests on washers I5, greater in number than the washers 45, to provide more tension for the spring and provide a slightly delayed closing action for the valve 58 with respect to the valve 46. The stem supports a valve 58 which is adjustable and a washer 59 which seats against the raised surface I9 to provide a sealV tight i'lt, similar to the syrup control valve.

Communicating with the bore 38b is a transverse opening 60 internally threaded to receive a threaded pipe 6| which is connected by acoupling member 62 to a conduit 63, in turn 'cone nected to a reduction valve 64. Connected to the other end of the reduction valve is a conduit 65 leading from a tank of charged water or other water (not shown). A threaded plug 66 closes the bottom of the bore 38o. The reduction valve acts to reduce the pressure from between 180 and 120 lbs. to 90 lbs. Communicating with the vertical bore 38a is a horizontal bore or passageway 61 which communicates with a vertical passageway 68 having an enlarged internally threaded portion 69, to which is threaded a valve body 10 having an externally threaded portion 1I and an internal bore 12. Threadedly secured to said valve body is a hollow cap 13. Fitting within the bore 12 is the stem portion 14 of the valve 15.'` A spring 16 is interposed between the valve head and the bottom of the cap to seat the valve head and urge it against the valve body 13, to close the bore 12. The cap 13 has a plurality of small apertures 11 spaced around the cap through which the charged water is dispensed. As will be clearly seen in Fig. 2, the water discharge member is positioned between the two syrup outlets. A nozzle 18 is threadedly secured to the base of the main body 26 and serves as a mixing wardly, opening the entrance to the bore 38a and allowing the charged water to pass under pressure from the opening 68 into the bore 38h, through the vertical bore 38a, the horizontal bore 61, and down the vertical bore 68. The pressure threaded willV cause the stem 14 to move downwardly unseating thevalve 15 and opening the entrance into-bore 12,l and the water will pass around the stem 14, around the valve head 15 and into the hollow cap 13 and through the port openings 11A into the mixing chamber 18 and through the nozzle 80. When the hand is removed'from the handle 35, the spring 51 will move the valve stem 55 back to its original position, and the actuating member 38 will likewise be pivoted back to its original position.

Adjustment of the ,cap V13 Vwith respect to the valve body 10 will determine the rate of flow as Well as the size of spray of the chargedwater. With the cap screwed in to its limit, as shown in Fig. 4, the spring 16 holdsthe valve head 15 tightly under vpressure against the underside of the valve body 10. As the charged water moves to unseat the valve head 15, a homogenizing action takes place as the water passes from between the bottom of the Valve body Vand the valve head, reducing the size of the globules of the CO2 gas to smaller dimensions, as well as restricting or retarding,Y the rate of ow of the water. The charged water passing through the ports 11 in the form of Va ne sprayY or stream which mixes with the syrup from the nozzle 58 in the mixing chamber 18, churns it up to get an even flavor throughoutv as it leaves the nozzle 88. By unscrewing the cap somewhat from that shown in chamber when syrup and water are simultaneously discharged; The lower end of the-nozzle Fig. 4 and reducing the pressure on the valve 15, the rate of iiow of the charged water is increased as is also the size of the globules of the CO2 gas. This cap can` be adjusted with respect to the valve head 48, to vdetermine the proper quantity of syrup with respect to charged water.

If it is desired to dispense one of the Syrups simultaneously with the charged water, then either one of thejhandles 34 or 36 (dependent on the Vsyrup desired) is movedforwardly. Assuming the handle 34 is moved, the actuating member 29 is pivoted forwardly,'and being in engagement with the lip 32 of themember 30, will simultaneously pivot the center actuating member 30 downwardly, causing both valve stems 43 and 55 to be simultaneously depressed. With a depression of the valve stem 55, the action previously described takes place. As the valve stem 43 vis depressed, moving the valve 46 away from the top of the bore k311), the Vsyrup in the container I8 (or 20) will flow by gravity from the syrup container through the conduit 23 into the bore 31a, andY through thespace 48 around the valve 46 and down past the needle valve 53 and through the non-,drip nozzle 5I)k into the mixing chamber 18,-where it is Ymixed with the charged water simultaneously coming from the apertures 11 rand asians the closingof the valve '58, thus closing the flow of Vsyrup prior'to the closing o`f 'the-charged water and permitting the charged water to flow Slightly longer than the syrup, cleaning `out any syrup that might be in the mixing chamber.

The needle valve 53 is adjustable to lregulate the flow of the syrup and is adjustable with respect to the valve l to determine the amount and quantity of syrup with respect to chargedk water to be dispensed. The needle valve 53 is spaced from the bottom of the bore 5|' so that as the flow of the syrup is interrupted by the needle valve, the ow will right itself before it leaves the bore 5|. The end of the nozzle represented by the bore section 52 acts as a shield for the flow of the syrup coming from the nozzle and serves to maintain the vacuum in the syrup nozzle. The action is as follows: When the valve head 42 moves upwardly after the handle has been released, pulling up the valve 46, it causes a suction in the bore 31h and creates a vacuum therein, and any syrup in the bore 5l will be trapped and held as a mass in bore 5I by this vacuum, thereby eliminating any dripping of the syrup when the handle is operated to cut the flow of syrup. When the handle is again operated and the valve 46 is unseated, the vacuum is broken and the syrup trapped in the bore will discharge into the mixing chamber and the flow will continue from the syrup receptacle by gravity.

In Figs. 6 and 7 are shown modications of a handle operating mechanism which is constructed to control the flow of one syrup in combination with charged water or charged water alone. The valve operating mechanism and other parts are identical in construction and operation to that described in connection with the syrup and charged water control members. In this modied construction however, there would be only one valve mechanism like that designated generally by the numeral 4| for controlling the syrup and one for controlling the discharge of water, like that designated generally by the numeral 54, hence only the construction of the actuating members will be described,

The actuating member 85 is shaped to provide cammed or 01T center surfaces 81 and 88 on both sides of the center 86, so that the valve operating member 89, which controls the flow of charged water, is depressed when the actuating member is rocked either forwardly or rearwardly. A cutout 90 is provided so that the syrup control member 9| is not engaged or actuated when the actuating member is moved forwardly, but will be engaged and depressed when the actuating member is rocked rearwardly. Thus the following action ensues. When the handle is moved forwardly, charged water is dispensed, when moved rearwardly charged water and syrup is dispensed. Y
